在 Couchdb ( 虹膜沙发 ） POST 请求中添加新文档失败，状态为 500

几个月前，下面的代码运行良好，用于在couchdb（iriscouch）中添加一个新文档。

现在我得到的是HTTP状态500。有解决方法吗？

代码（在节点.js中）：

var http=require('http');
var options = {
  host: 'sbose78.iriscouch.com',
  path: '/bosedb1',
  method: 'POST',
  headers:{
 'Content-Type':'application/json',
 'accept':'application/json'
   }
 };
var data={
   'servings' : 4,
   'subtitle' : "Delicious with fresh bread",
   'title' : "Fish Stew------"
};
var req = http.request(options, function(res) {
   console.log('STATUS: ' + res.statusCode);
   console.log('HEADERS: ' + JSON.stringify(res.headers));
     var body="";
   res.on('data', function (chunk) {
     body+=chunk;
         console.log('BODY(inside listener):'n ' + body);
   }); 
  console.log('BODY (outside listener): ' + body);
});

req.on('error', function(e) {
  console.log('problem with request: ' + e.message);
});

 //write data to request body
req.write(JSON.stringify(data));
req.end();

回应：

    STATUS: 500
HEADERS: {"content-type":"text/plain","content-length":"239"}
BODY(inside listener):
 Internal routing error
